Investigation of Kinetics of Supercritical Drying of Alginate Alcogel Particles

, 2019
Spherical calcium alginate gel particles were synthesized by dripping method. The effects of temperature, pressure, particle size and CO2 flow rate on kinetics of supercritical drying of alginate gel particles in a packed bed were investigated.

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods. [PDF]

Chirality
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and
